Garage Door Spring Types in Salem: Torsion vs. Extension Explained
2026-07-05 7 min read
In 15 years servicing Salem garages, I've seen homeowners confused about one thing more than almost anything else: which type of spring their door actually has, and why it matters. The answer is simple. Most residential doors use either torsion springs or extension springs, and understanding the difference could save you money, headaches, and a serious safety risk.
What Are Torsion Springs vs. Extension Springs?
Torsion springs sit horizontally above your garage door opening. They twist and wind as your door opens and closes, storing and releasing energy. Extension springs hang vertically on each side of the door. They stretch and contract, like a rubber band, to lift the weight.
Here's the key difference: torsion springs are more durable, safer, and more common in modern homes. Extension springs are cheaper upfront but wear faster and pose a higher injury risk if they snap.
Most Salem homes built after 1990 have torsion springs. Older properties or budget installations often have extension springs. If you're unsure which you have, look above your door. See a horizontal wound coil? That's torsion. See springs running up the sides? That's extension.
How Long Do They Last?
Both types typically last 7 to 9 years with normal use, assuming you open and close your door 4 to 8 times daily. A spring is rated for roughly 10,000 to 15,000 cycles. Do the math: that's about one cycle per opening and closing, so every lift counts.
Climate matters too. Salem winters are tough on garage doors, and cold weather makes springs more brittle. Ice buildup adds weight, forcing springs to work harder. Check out our detailed guide on why Salem winters are so hard on garage doors and what to do about it for more context.
Life expectancy also depends on maintenance. A door that's well balanced and properly lubricated will keep springs healthy longer. Neglected doors with rusty tracks or misalignment? Springs fail faster.
Why Torsion Springs Are Usually the Better Choice
Torsion springs distribute weight more evenly across the door. They're engineered to handle the full load, which is why they last longer. One snapped torsion spring can sometimes be balanced temporarily, though replacement is the safe move.
Extension springs, by contrast, work in pairs. If one snaps, the other can't hold the load alone. A snapped spring also means the door becomes a safety hazard. The weight drops unpredictably, and the spring ends can whip around like a weapon.
That's not hyperbole. I've seen injuries from extension spring failures. Never attempt a DIY repair on either type. The tension is extreme, the springs are under high pressure, and mistakes cause serious harm.

Replacement Cost and What to Expect
Spring replacement cost depends on the type and your door's weight. For Salem homes, expect $200 to $400 for a single torsion spring, $150 to $300 for an extension spring pair. Labor typically runs $150 to $250 more.
Why the range? Heavier doors (like insulated or steel models) need stronger springs. Custom sizes cost more. And if your door is older, finding exact replacements takes time.

Signs a Spring Needs Replacement Soon
Your door opens slowly or unevenly. One side rises faster than the other. That's a spring losing tension. You hear loud creaking or grinding sounds. The door feels heavier than usual. These are warnings, not death sentences, but they mean replacement is coming.
A snapped spring creates an instant emergency. The door won't open, or it crashes down suddenly. If your garage door spring snapped in Salem, here's what to do right now. Don't try to force the door open. Call a professional for same-day service.
Maintenance Tips to Extend Spring Life
Lubricate springs twice a year with a garage door specific lubricant. Not WD-40. Use a product designed for springs and hinges. Keep tracks clean and aligned. Check the door balance monthly by disconnecting the opener and manually lifting the door halfway. It should hold position without drifting.
Have a professional inspect springs annually. Small problems caught early prevent costly failures later. Our full list of garage door services includes spring inspection as part of routine maintenance packages.

Frequently Asked Questions
Can I replace just one spring if the other is still working? No. Springs wear at similar rates. Replacing one creates imbalance and puts extra strain on the survivor. Both should be replaced together for safety and even door operation.
How do I know if my spring is torsion or extension? Look above your door. Torsion springs run horizontally across the top. Extension springs run vertically along both sides. When in doubt, call a technician to confirm.
Is spring replacement covered by homeowner's insurance? Usually no. Spring failure is considered normal wear and tear, not damage. Check your policy, but most plans don't cover it. That's why maintenance matters.
How much does emergency spring replacement cost in Salem? Same-day or after-hours service typically adds $75 to $150 to standard labor. The sooner you call, the sooner we can schedule. Phone (978) 717-0808 or schedule a free quote to discuss your situation.
Can weather affect how fast springs wear out? Absolutely. Cold temperatures make metal brittle, and freeze-thaw cycles stress springs. Salem winters accelerate wear. Regular maintenance and annual inspections help offset seasonal stress.
